Our industry creates values


Inorganic coagulants are pivotal for safe drinking water and efficient wastewater purification. They
are produced in Europe, thus ensuring a reliable local supply.


Chemical water treatment is the most energy efficient water treatment technology and has a low carbon footprint.


Coagulants are essential for protecting human health and improving environmental performance. INCOPA members are committed to the highest product quality and environmental standards in Europe.


Chemical water treatment is the most cost efficient and state of the art technology. Coagulant use represents only 0.5% of the total cost of water purification (0.5€ on 100€, per person per year).


Our products, as well as their applications, contribute to the Circular Economy: thanks to
the use of inorganic coagulants 1/3 of the phosphorus used in Europe could be recycled.
